  • Pricing gets real at scale
Kai's verdictA-tier for the right use case. Not for solo devs. If you manage engineers, try one license.A-tier. The right answer if you want open-source + terminal-native + model-agnostic.A-tier. Amazing when it works, frustrating when it doesn't. Runway still more reliable for pros.S-tier for open-source model APIs. The default in this space.
